OAXACA, Mexico – Adela María Gutiérrez fell ill April 1 with what she thought was a bad cold. She tried aspirin and antibiotics, bed rest and moist towels, but nothing brought down her soaring fever, reduced her aches and pains or boosted her energy level.

It would be eight days before Gutiérrez went to Oaxaca's general hospital, where she arrived listless and barely able to breathe, her extremities blue from a lack of oxygen.

That delay in getting expert help may explain why Gutiérrez, 39, a mother of daughters ages 10, 17 and 20, became Mexico's first death from a new, virulent strain of influenza A (H1N1). It may also explain why Mexico's death toll from the virus is higher than anyplace else's.

Epidemiologists are still puzzled by the virus, its origins and its modes of transmission. But they agree that prompt medical attention is crucial to treating it. That has been where Mexico, which has had 12 confirmed deaths due to the new virus, lags far behind. A number of other deaths may have been caused by influenza A.

“People wait too long to go to doctors,” said Dr. Marcelo Nogera, undersecretary of health for Oaxaca state. “That's a problem here in Mexico. If we can treat a disease like this early, we can stay ahead.”

There may well be other factors to explain why patients in Mexico like Gutiérrez, whose medical records show a desperate, belated scramble by a team of doctors to keep her alive, are dying at what appears to be a higher rate than swine flu patients elsewhere.

Researchers speculate that one reason some of the Mexicans died was that they had other major health problems.

But medical officials say the most important factor may be the eclectic approach to health care in Mexico, where large numbers of people self-prescribe antibiotics, swear by homeopathic medicine or seek out vitamin injections. For many, only when all else fails do they go to a doctor.

“I think it has to do with the culture, the idiosyncrasies of Mexicans,” said Dr. Nicolás Padilla, an epidemiologist at the University of Guanajuato. “The idea is that I don't go to the doctor until I feel very bad.”

There are logistical reasons, as well, that compel Mexicans to steer clear of hospitals. At overcrowded public facilities, they complain, they are often turned away, treated by indifferent doctors or made to wait endlessly.

In the case of Gutiérrez, it took her three days to go to a doctor at a small clinic near her home. She was told she had a throat infection and should take antibiotics. As her condition worsened, she sought other opinions but still avoided the hospital. On her third consultation, a doctor told her she had pneumonia and sent her to the hospital.

Once she was admitted, health officials appear to have acted quickly. A laboratory test found an unusual virus.

The ward she had shared with at least 20 seriously ill patients was quarantined. State and federal health authorities were notified.
